Which navigation OS version?

[DumfriesDik]

I have a problem with my navigation OS and I am trying to correct it, i have started another thread, sorry. I have found a link that looks promising, but which version of the OS do I need?

V25, V29, V30, V32

Is the latest the best or will that mean that my old 2007 sat nav disc will not work?

v32 is the latest firmware, your maps disc will work fine with it
